Ok, so I set up my 2checkout script, but I still have problems.
My customers are not returning to the site the way they should.

I’m using the MD5 encryption method with the secret word to verify my orders.
When I test this in DEMO mode, using “1″ (without the quotes) as the “order_number”, it works perfectly fine.

But, with real orders (not in DEMO mode), the script doesn’t work. When not using demo mode, I use $_POST['order_number'] as the order number coming from 2checkout.

For some reason, there is still something missing.

Any ideas?
I mean…if demo mode works, why can’t real orders work as well? The only difference is the “order_number”, right?
